Answer:
72%
Step-by-step explanation:
There are a total of 50 quizzes in the year
From the first 20, the student passes 60%. This makes a total of
12 passes
Out of the remaining 30 quizzes the student passes in 80% of them. This makes a total of
24 passes
Adding the two values
12 + 24 = 36
The student passes 36 quizzes out of 50.
We convert this to a percentage
%
Answer:
(5,6)
Step-by-step explanation:
8X +6Y=4
Y=-3X+9
Substitute the second equation into the first. Every place you see y put -3x+9)
8x +6(-3x+9)=4
Distribute
8x-18x +54 = 4
Combine like terms
-10x +54 = 5
Subtract 54 from each side
-10x +54-54=4-54
-10x = -50
Divide by -10
-10x/-10 = -50/-10
x= 5
Now we need to find y
y = -3x+9
y = -3(5) +9
y = -15+9
y= 6
(5,6)
The ends of the graph will extend in opposite directions.

Answer:
The ounces of oil needed is 5 ounces of oil
Step-by-step explanation:
The first thing to do here is to calculate the volume of the lemon-scented candle given.
Looking at shape the volume can be calculated using the formula L * B * H
where L(length) = 10cm , B(breadth) = 8cm and Height(h) = 25cm
The volume V is thus = 10 * 8 * 25 = 2,000 cm^3
The ounces of oil needed for the candle to have 0.0025 ounces of oil per cm^3 of wax will be = The volume of the lemon-scented candle * 0.0025 ounces of oil per cm^3 of wax
That will be = 0.0025 * 2,000 = 5 ounces
Answer:slope of line is 5/7
Explanation:The slope of the line can be calculated using the following rule:
slope =
The given points are:
(-9,-10) which represent (x1,y1)
(-2,-5) which represent (x2,y2)
Substitute with the points in the above equation to get the slope as follows:
slope =
= 5/7
